SPECIFICATIONforming part of Letters Patent No. 716,144, dated December16, 1902.

Application filed March 1 7, 1902.

To all whom it may concern:

Be it known that I, ADOLE' TELLsoHow, manufacturer, a subjectof theGerman Emperor, residing at 27 Grnauerstrasse, Berlin, Germany, haveinvented cert-ain new and useful Improvements in Embossing-Presses; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a machine for color-embossing envelops,prospectuses, and the like. i

The machine is so designed that if the gripper for lifting the separatesheets of paper or the like from the pile should for any reason fail toact and supply a sheet under the die all the operative members of themachine for embossing and supplying the die with colorl will beautomatically thrown out'of gear.

In order that the invention maybe readily understood and carried intoeffect, I will describe thesame with reference to the accompanyingdrawings, in which is shown a convenient constructional form of machineembodying my invention and which is capable As my inventionmay beemployed in con-` nection with various forms of printing or embossingmachines, I have in the accompanying drawings illustrated only theimportant parts of such a machine, and such illustrahowever, that thedrawings will illustrate the manner of applying my invention to anysuitable printing or embossing machine and that a detailed illustrationof such a machine is unnecessary.

Figure l is a front elevation of the machine, partly in section. Fig. 2is a side elevation. Fig. 3 is'a plan, and Figs. 4, 5, 6, and7showdetails. Fig. 8 is a front elevation of a complete machine embodyingmy improvements. y

In the middle of the table 1 of the machine isisituated the press-head2, in which is to be rotated through the intervention of anadjacently-placed vertical driving-shaft 4, in

conjunction with a toothed segment 5 and pinion 6, in such a manner asto move the upper die downward. The papers-in this case unfoldedenvelops--are piled at the left of the machine at 8, and a suctiondevice 9, of known construction, lifts the upper envelop a little,lso asto enable a gripper to pull such envelop off the pile and carry it overthe table 1 to the press-bead 2, Where it strikes against stops andremains there whilethe descending die 7 eects the operation ofembossing. This gripper, which may be of any suitable construction andis conventionally illustrated at in Fig. 8 of the drawings, moves fromthe right-hand side of the machine in a suitable guide beneath thepress-head 2 toward the left, whereupon it grips the uppermost envelopand withdraws the same at its back stroke for the purpose previouslystated. The slot 10 at the front side of the machine-table 1, (Fig. 3,)indicates the path of said gripper. Above the pile of blank envelops isdisposed a horizontal shaft 1l, (Figs. 1 and 3.) This shaft carries twodepending small levers 12, which reach down into the plane of the pileof envelops in such a manner as to rest against the inclined sidesthereof, (Fig. 3.) If now the uppermost envelop is lifted by the gripperand dragged over the machine-table in the direction indicated by thearrow, the two inclined side edges of the cover will slide along the twolevers l2 and lift the same, so imparting a slight angular motion to theshaft 11 each time after the gripper has correctly picked up theuppermost envelop and carried it to the presshead, whereupon the nextaction is as follows: In the lower part of the press-head 2 is mounted ahorizontal shaft 13, which projects from both sides of the head 2 and isfitted with a lever at each end. To the end of the shaftf13 nearest tothe pile of envelops is fixed a broad fiat lever 14E, which hangs downvertically and has a hole 1.5, (Figs. 1, 3, and 7.) At the top of thislever 14 is' mounted at 16 a second two-armed lever, the lower leverarm18 of which is provided at its lower end with a weight 17, which whenthis leverrin consequence of its own weight gravitates to a verticalposition occupies a position just in IOO front of the hole 15 in thelever 14, so that the said hole 15 is thereby covered, (Figs. 1 and 7.)The upper lever-arm 19 of the aforesaid pendulum-lever points verticallyupward and is connected by means of a thin wire rod 20 to a lever 21,fast upon shaft 11. If now the uppermost envelop is picked up from thepile by the gripper, so that said envelop moves the two levers 12, andthereby also the shaft 11, the lever 21 will also be caused to move, andthus pull by means of the rod 20 the lever-arm 19 from its verticalposition. This motion is indicated in dotted lines in Fig. 1. The lever21 has thereby performed an angular motion toward the left and has alsomoved the lever-arm 19 toward the left, so that the lower arm 18 ismoved toward the right, and the weight 17 thereby uncovers the hole 15in the lower end of the lever 14. The uncoving of this opening 15 hasthe following purpose: As will be seen from Fig. 3, there is mounted inthe frame of the machine and to the rear'of the press-head 2 ashaft 22,which by means of an eccentric, a crank-disk, or a similar mechanicaldevice and through the intervention of a push-bar 23 impartsreciprocating motion to a bar 25, adapted to slide in a sleeve 24. Thisbar 25 is disposed within its sleeve sidewise of the press-head 2 insuch a manner and its travel is so regulated that at each stroke of theeccentric it is caused to enter the plane of the depending lever 14 infront of it. When the previously-described oscillation of the lever-arm19 toward the left and that of the lever 18 toward the right takesplace, the bar 25 moves forward and can freely pass through the hole 15in the lever 14 and is equally free to withdraw. This hole 15 is, asbefore described, uncovered when the gripper has properly picked up thetop envelop from the pile. Should, however, the gripper for any reasonfail to pick up the envelop, the shaft 11 will remain stationary, andthus the lever 21 does not move the lever 19, and the hole 15 inthelever 14 remains closed. As the shaft 22, and consequently also thepush-rod 23, operate independently of the motions of the aforementionedlever, the rod 25 still performs its forward motion. When this rod 25thus moves forward into the plane of the lever 14, it will be preventedfrom passing, as before, freely through the hole l5 and only strikesagainst the weighted disk 17, covering the said hole, and thus producesan oscillation of the lever 14 in the direction toward the front of themachine, as is indicated by dotted lines in Fig. 7. As before stated,the other end of the shaft 13, mounted in the press-head, is also fittedwith a downwardly-depending lever 26. This lever serves to utilize themotion of the shaft 13, produced as before described, for disengagingthe press-spindle.

To the rear of the press-head 2 is mounted a second shaft 27, arrangedhorizontally in the frame of the machine and parallel with the shaft 22and fitted with a long at lever 28, (Figs. 2 and 3.) The said lever 28is at its outer end broadened to a plate which is provided with a hole29, similar to that in the aforesaid lever 14, (Fig. 5.) The shaft 27 isdriven by the main shaft 22 through the intervention of an eccentric orthe like in such a manner that the lever 28 is caused to perform aslight oscillation from its horizontal position upwardly, as indicatedin Fig.2.

Upon the flat perforated end of the lever 28 is mounted a two-armedlever fulcrumed at 30, the arm 31 of which is formed with a disk-shapedend 32, while the other lever-arm 33 is proportionately short. Theentire lever 28, as previously described, is so mounted in themachine-frame-z'- e., fixed upon the shaft 27-as to cause the eXtremeedge of the outer plate to be near the press-head 2. The twoarmed lever31 33 is so mounted upon the lever 28 as to cause its short lever-arm 33to rest against the lever 26, depending from shaft 13, as aforesaid, andas shown most clearly in Figs. 2 and 5. If the lever 26, in consequenceof the rotary movement of the shaft 13, moves into the position shown indotted lines in Fig. 2, it will slide the short lever-arm 33 in front ofit, so that in this manner also the other lever-arm 31 is displaced. Asseen from Fig. 5, the two-armed lever 31 33 when in its normal positionis so situated that the opening 29 of lever 28 is not covered by thedisk'32. If, however, the two-armed lever 31 33 is in consequence of themotion of lever 26 moved into the position shown in dotted lines, thedisk 32 covers the hole 29 in the lever 2 8.

Above the end of lever 28, which carries the two-armed lever 31 33, ismounted a vertical rod or plunger 34 in a bracket 35, fixed tothemachine-frame. As previously stated, the lever 28 makes a slight upwardoscillation and takes at every stroke the dotted position, Fig. 2.During this movement the hole 29 receives the lower end of the rod orplunger 34, so that the position of this latter remains unaltered. If,however, the hole 29 is covered by the disk 32 at the end of thelever-arm 3l, (which occurs when the gripper has failed to pick up anenvelop from the pile as naturally,) the hole 29 cannot permit thepassage of the rod 34, which latter is, on the contrary,opposed by aneffective surface, and the lever 28 at its up motion lifts the bar 34 inits guides for a definite distance.

Sidewise of the bracket 35 is mounted the driving-shaft 4for the spindle3, said shaft receiving its motion from a curved arm 36, connected by abolt 37 to the push-rod 38, so that the toothed segment 5 operates thepinion 6, and thereby also the press-die. The push-rod 38, (Fig. 2,) ismoved, as indicated by kthe arrows, through the swinging action of alever 39. The bolt 37, which transmits the motion of the push-rod 38onto the shaft 4, is not fitted in the usual manner in an eye at thefront end of the push-rod 38. The latter is formed at its fore end witha long slotted slide- IOO IIO

guide. In this slide-guide is fitted a block 40,

in which is mounted the bolt 37. "The otherl ing with its front endagainst the block 40, so

that it cannot move in the said slide-guide.

Therefore in this` manner the reciprocatory movement of the push rod 38operates the;

shaft 4, and thereby also the press spindle, in the normal manner. 41 islifted and the space previously occupied by it left clear, the push-rod38 willno longer be able to move the block` 40 and bolt 37. On thecontrary, the block 40 remains stationary, so that the shaft 4 will notbe moved,

and the press-spindle 3 also becomes stationary, This disengagement ofthe pawl 41 occurs when the gripper has failed to pick up, remove, anddeposit an envelop beneath the die, so that the downstroke of the presslspindle 3 is Vnot required, and the latter is then disengaged in thefollowing` manner: The bolt 42, whichpcarries the pawl 41 and which ismounted at the rear end of the slidepath of the push-bar 38, projects atone side beyond the push-bar, and to such end is secured a lever-arm 43.This lever-arm is bent downward and rests uponthe roll 44 at the upperend of the bar 34, upon which latterit moves along during the to-and-fromotion of the push-bar 38. If now by the action of the two-armed lever3l 33, in conjunction with the previously-d escribed operative parts,

lthe bar 34`is pushed upward, the lever-arm 43 moves also upward, andthe pawl 4l clears the path` of the push bar 38. The consequence of thismotion is that the push -bar 38 is reciprocated without taking alongwith it the bolt 37. ary and no impression. is produced.' When after aworking stroke the aforesaid disengagement'takes place, it` may in somecases `happen that the toothed segmenty moves slightlyl back, so that inthis manner the stationary position of the press-spindle may becomeinaccurate, and in order to prevent this the following arrangement isprovided: Beneath the arm 36 upon shaft 4 is fixed a leverarm 45, Figs.1, 3, and 4. Further, upon the bar 34 is iixed a laterally-proj ectinghorizontal lever 46, upon which a hook 47, pivoted at 48,'

loosely rests. With the normal position of the bar 34-t'. e., when sameis not elevatedn the lever-arm 45 swings freely over the pawl 47,whereas when said bar 34 is elevated the lever 46 also rises with it andlifts the hook 47, as shown in dotted lines in Fig. 1. This hook 47 isthus placed in the path 'of the lever 45, which at its next movementstrikes against said hook 47 and is thus stopped in its path. Therebythe shaft 4and the toothed segment 5 are suddenly stopped and heldstationary, so that the backing and the down motion of the press-die isrendered impossible. As stated hereinbefore, not only is thepress-spindle disengaged when the gripper If, however, the pawl` Theshaft 4 remains station` l fore the arrival of the envelop to beembossed by the die caused to move out of the head 2, and its path is sodisposed as to enable it to slide lightly with its rollers over thelower die 48a, andthus supply the latter with the requisite color. Thecolor-truck receives the color upon its rollers in another end positionfrom a color-box provided at the back of the press-standard similarly asin a platen--press and which in the figures is shown only in outline. Atright angles to and beneath the path of the color-truck 49 is mountedthe previously-mentioned shaft 13. This shaft is in the interior of thestandard fitted with a small tappet 52, Fig. l, upon which one of thesides of the color-truck reposes. When the shaft 13 moves,V while thegripper fails to pick up an envelop, the tongue 52 swings a little inthe upward direction, whereby the colortruck 49, arriving shortlyafterward from the rear, is consequently also slightly lifted, asindicated by dotted lines in Fig. 6. The color-rollers during the saidforward movement of the truck do not, therefore, come into contact withthe lower die 48a, so that it receives no color when the envelop failsto arrive and the upper press-die is stopped from descending. If thepreviously described color mechanism were allowed to act so as to causethe color-truck 49 to furnish the die 48iL with color whether thegripper supplied the envelop or not, it will be clear that the die wouldreceive too much colpr, and thus not produce a clear and sharpimpression. By means of the invention hereinbefore described anembossing-pressis caused to produce a very clean impression. and Worksina Very economical manner and without any waste. By preventing all theoperative parts upon which a really good impression depends fromperforming any unnecessary` movement their wear and tear is reduced to aminimum and the life of the machine is increased.
